DECK-LAMP LGHTING FIXTURE.

Appnetion mea March 8,1923. serial No. 623,575.

To (1U fui/0m it may concern.'

` Be it known that l, llnwAnn J. Sonnonnnn, a citizen of the United States7 residing at 281Summit i/Xvenue, Summit, in the county of Union and State of New Jersey, have .invented certain new and useful Improvements in Deck-Lamp Lighting Fixtures, of which the following is a specification.

This invention relates to a deck lamp lighting fixture, and the novelty consists in the adaptation and arrangement of the parts, as hereinafter fullypointed out.

There are various types-of lightingfixtures having shade holders which are adapted to hold the lighter forml of shades in a secure manner, and in sucha way that they will not be readily broken. But there is a large demand for a liXture embodying a shade holder adapted to hold a larger and heavier type of shade vinl a secure manner, and also in a way which will not cause breakage under unusual conditionsvprevailing on steamships andrailroad trains'. I

Such a device must also permit theeasy. and quick removal and replacementof the shade for cleaning or replacement'in case. of breakage. My device meets all of these requirements, furnishing a shade holder `which firmly and securely grips a shade of a heavy type if desired and permitting the easy and quick removal of the shadefor cleaning .and restoring to position in the fixture again. Mv device also is adapted to facilitate the operator in the removal of the shade bythe operative releasing l'means pulling downward, which is the natural direction for the operator --reaching upto ceiling fixtures of this type. A` 'y Y Referring'to the drawings; Figure 1 is a vertical sect-ion of my device showing the electrical connecting means; Figure 2 is a side elevationof the spider; Figure 3 is a top plan view of Fig; 2. 'Figurel is a top plan view of the iinger clamping device; and Figure 5 is a side elevation of the same. In the drawings 10 is al spider adapted lo be rigidly secured to the ceiling where the iixture is vtoy be used by means of suitable screws 11 whichpass through the borings 19 in the spider 10, and said spiderl() has a dent-ral internally threaded boring12 adapted to receive an externally threaded socket support member "13, y to which is n'icnnted at its lower end in theusnal inanneij a socket 14k of usual constructioin A locking nut 2O threaded over the upper eX- tcrnal threading of said socket support n'ieinber 13 is adapted to be screwed against the spider 10 after the socket support 13 has been screwed into position in said spider l0, in order toflock said socket vsupport member 13 into position and support the saine against horizontal pressure. Electrical wires 1F are adapted to pass through thel spider 10 and the socket support V13 land be connected with the socket 14 in the usual well known manner.

A canopy 16 is adapted to be cured to the spider 10 by means of suitable screws 17 engaging internally threaded boring 18 of the spider 10.` The canopy 16 has at its lower edge an outturned flare 21, which has a beveled face 22 on the inside thereof, and there are slots or openings 23 through the sides of said canopy 16. A thickened portion 24 on the inside of said canopy 16 terminates at its upper portion in a cylindrical flange 25 having an external threading 26, over which `a cylindrical connector member 27 is adapted to be threaded. The connector member 27 h as an internal threading28 around the inside of the upperedge thereof7 anda cylindrical member 29 hav- Ving an external flange 30-at its lower edge and around which '.isf mounted a spiral springl 31 has Vanexternal threading 32 at its upper edge adapted to engage the linter'- vnal threading 28 ofthe connector 27. A

cylindrical sliding member33 having an' inturned cylindrical flange 345 around its upper edge is adapted to bemounted between the cylindrical member 29 and the canopy 16 so that the flange 311 will rest onV the upper part of the upper end ofl the, spiral spring 31 so as to be under the constant Iiipward spring tension 'of the spring 31, which at-its lower end rests on the flange'30y of the cylindrical member 29. Internally threaded collarmembers 35 are adaptedto be screwed Vinto the sliding cylindrical member 33 at 36s() Vthat said collar members 35 register in the slots 23of. the canopy 16. An annu# lar ring 37 is adapted to be mounted around the canopy16 by means vof screws 38 which are adapted to thread into the internal threading of the collars 35, thereby rigidly securing the annular `ring37 to theslidi'ng cylindrical memberl 33. A cylindrical finger clamping member 39 having holes 40 therein is adapted to be rigidly secured by means of serefws] i1- through said holes 40 to the base of the sliding cylindrical member 33t rigidly Se;

The spring clamping member 39 has individual finger members 42, the lower portions of said fingers 42 forming reversev curves so as to be adapted to grip the upper outturned ange 43 of a shade-44.

In assembling my fixture the spider l0 will be first rigidly secured'to theceiling by means of screws 1l, and the connecting wires lwill then be run through the socket support' 13 which will be rigidly screwed into position in the internal'boring 12, and the locking nut 2O threaded onto the upper end of the socket support 13 willthenbe turned up tightly in positionl against the spider 10. Thesocket l4will thenbe connectedto the wires l5 in the -usualmannerandrigidly secured in position to thelower end ot the socket support 13Lin1thev well linownmanner.V The connector member 271 will* then bescrewed in position over the-threaded portion 26 of the cylindrical' flange- 25 of the thickened portion 24" of the canopy 16. p Thespiralv spring 3l will then be placed inA position around the cylindrical member 29A so as to rest on the external flange' 302 of thesame, and' the cylindricalA sliding member33 will be slid over the upper end` of said cylindrical? member 29 and? the spring 3l sothat the inturned circular iflange 34' of the sliding member 33 will: res-t7 onthe upperv end` off the.: spiral spring- 31, and these twocylindrical membersr29 and.' 33 with the spring 31 between them will then vbe mounted-'within'.the canopy 16: by screwing the cylindrical member 29 by means ofthe external threading 32 into the internal! threading 28 of theV connector member- 27'. 'Ilhe` collar members 35: cangthen be screwed imposition: into the cylindrical member 33v atl 36 througlrthei openings 23 in the' canopyf 16',` and theannular ring 37 can then be rigidly) securedl to the`- sliding member 33" byA means of screws 38 adapted to be screwed into the collar,` members 35. The` cylindrical' finger clamping member 39 can then be rigidlysecured to the base of the sliding member 33 by means of screws 41. The canopy 16 together with theassembled parts therein can then be rigidly: secured to the spider l0 by means vof screwsflf..

In operating my device tlieoperator need only` pulldown onthe annular; ring 37;.therebyV compressing `the spring 311v and' releasing the cylindrical finger; clamping member" 39 from 1 its normal tensioni againstf the beveled face 22 off the,fmt-turned:v flare 21:bf= the canopy 1G,y whereupon the; fingers142'of the cylindricali finger.r clamping` member 39' are refleasedso that the globe 44'may beslipped into positionor removed4 therefrom quickly an'd'e'asily withoutitl'ie danger ofr cracking or vbreaking thesame'.I

It will be understoodthat an electric light bulb of" usualiconstruction` is adapted to be mounted in the" socket 14 for purposes of illumination.

Many. variations may be made in my device Without departing from the spirit and intent of the invention.

I claim:
